Exercise as Medicine: How ‘Prehabilitation’ Could Revolutionize Cancer Treatment
Imagine a future where preparing for cancer treatment is as much about building strength as it is about battling the disease itself. A small but groundbreaking clinical trial at the Royal Surrey NHS Foundation Trust is suggesting just that – that moderate to intense exercise, undertaken before and during cancer treatment, could significantly improve outcomes, and even render some tumors undetectable. This isn’t about adding another burden to an already overwhelming journey; it’s about empowering patients to take control and potentially rewrite their prognosis.
The Rise of ‘Prehabilitation’ and its Early Successes
For decades, the focus during cancer treatment has been largely reactive – addressing the disease and mitigating the side effects of aggressive therapies. But a growing body of research, and now this new study, points to the power of cancer prehabilitation, a proactive approach that aims to build resilience before treatment begins. The Royal Surrey trial, focusing on patients with oesophageal cancer, involved a 16-week exercise program incorporating cycling and strength training for half of the participants. The results? Authors, in partnership with the University of Surrey, report that in some cases, tumors were “undetectable” during surgery following the program.
“If you have been diagnosed with oesophageal cancer this is the time we can give you some sort of ownership over your journey,” explains Dr. David Bartlett, co-first author of the study. This sentiment underscores a crucial shift in the patient-physician dynamic – from passive recipient to active participant.
Beyond Oesophageal Cancer: A Broadening Scope
While the initial trial focused on oesophageal cancer, the principles of prehabilitation are being explored across a range of cancer types. Researchers believe the benefits extend beyond simply shrinking tumors. Exercise strengthens the cardiovascular system, improves muscular strength, and boosts the immune system – all critical factors in tolerating the rigors of chemotherapy, surgery, and radiation. This translates to fewer complications, shorter hospital stays, and an improved quality of life.
Pro Tip: Even if you aren’t currently undergoing cancer treatment, incorporating regular moderate to intense exercise into your routine can significantly improve your overall health and resilience. Consult with your doctor before starting any new exercise program.
The Science Behind the Strength: How Exercise Impacts Cancer
The mechanisms by which exercise impacts cancer are complex and still being unravelled. However, several key pathways are emerging. Exercise reduces systemic inflammation, a known driver of cancer progression. It also improves the delivery of oxygen and nutrients to tumor cells, making them more vulnerable to treatment. Furthermore, exercise can modulate the immune system, enhancing its ability to recognize and destroy cancer cells.
“Cancer takes away a lot of things and you can feel a little bit like a passenger,” shares Mike Milton, a patient participating in the Royal Surrey trial. “It can be quite a dark time and this gives you something to focus on that you can control.” This highlights the psychological benefits of prehabilitation – a sense of agency and empowerment that can be profoundly impactful during a challenging time.
The Role of Personalized Exercise Programs
One size doesn’t fit all when it comes to exercise and cancer. The optimal program will vary depending on the type of cancer, the stage of the disease, the patient’s overall health, and their individual preferences. Increasingly, hospitals and cancer centers are incorporating exercise oncology specialists – healthcare professionals trained to design and supervise personalized exercise programs for cancer patients. This individualized approach is crucial for maximizing benefits and minimizing risks.
Expert Insight: “We’re moving towards a model where exercise is considered as essential a component of cancer care as surgery, chemotherapy, and radiation,” says Dr. Kerry Courneya, a leading researcher in exercise oncology at the University of Alberta. “The evidence is mounting, and the potential benefits are too significant to ignore.”
Future Trends: From Clinical Trials to Standard of Care
The Royal Surrey trial is a promising first step, but larger, more comprehensive studies are needed to confirm these findings and establish clear guidelines for implementing prehabilitation on a wider scale. Several key trends are shaping the future of exercise and cancer:
- Remote Monitoring & Digital Therapeutics: Wearable technology and mobile apps are enabling remote monitoring of patients’ exercise adherence and physiological responses, allowing for personalized adjustments to their programs.
- Integration with Cancer Registries: Linking exercise data with cancer registries will allow researchers to track long-term outcomes and identify which patients benefit most from prehabilitation.
- Expanding Access to Exercise Oncology Specialists: Addressing the shortage of trained exercise oncology professionals is critical for ensuring equitable access to this potentially life-changing intervention.
- Focus on Survivorship: The benefits of exercise extend beyond treatment. Exercise can help cancer survivors manage fatigue, improve physical function, and reduce the risk of recurrence.
Did you know? Studies have shown that even moderate exercise, such as brisk walking, can significantly reduce the risk of developing several types of cancer, including breast, colon, and endometrial cancer.
Implications for Healthcare Systems and Patients
The widespread adoption of prehabilitation could have profound implications for healthcare systems. By reducing complications and improving outcomes, it could lower healthcare costs and improve the efficiency of cancer care. However, significant investment in infrastructure, training, and research will be required to realize these benefits.
For patients, the message is clear: exercise is not just a complementary therapy; it’s a powerful tool that can empower you to take control of your cancer journey. Talk to your doctor about whether prehabilitation is right for you, and explore the resources available to help you get started.
Frequently Asked Questions
Q: Is exercise safe during cancer treatment?
A: Generally, yes, but it’s crucial to consult with your doctor and an exercise oncology specialist to develop a program that is tailored to your specific needs and condition.
Q: What type of exercise is best for cancer patients?
A: A combination of aerobic exercise (e.g., walking, cycling) and strength training is typically recommended. The intensity and duration will vary depending on your individual circumstances.
Q: Can exercise prevent cancer recurrence?
A: While more research is needed, studies suggest that regular exercise may reduce the risk of cancer recurrence and improve survival rates.
Q: Where can I find an exercise oncology specialist?
A: The American College of Sports Medicine (ACSM) and the Cancer Exercise Training Institute (CETI) offer directories of certified cancer exercise trainers. See our guide on Finding a Qualified Cancer Exercise Professional.
